We have took in a stray puppy so we do not know all of her habits, we took her to the Vet right away because she had ticks & flea all over her when she wondered into my husbands work. The vet gave her shots, and said she is about 8 weeks old. My questions her skin is very hot to the touch on her stomach and she does not have a lot of energy. Today her nose seems dry.. Any ideas can this be normal for a puppy?
